What to do if the Fuso莲花 is infested with scale insects
Fuso莲花, as a popular variety of succulents, is loved by gardening enthusiasts for its unique lotus-like shape. However, infestation by scale insects often leads to growth stagnation or even death. This article systematically analyzes the full process of pest manifestation and management solutions.
Characteristics of Fuso莲花 Scale Insect Damage
Immediate inspection is required when plants show signs of slow growth or increased leaf spacing:
Obvious Symptoms of Pest Infestation
White fluffy masses, 0.5-2mm in diameter, can be seen on the back of the leaves, with semi-transparent waxy bodies and clearly visible antennae. Root systems show brown, watery lesions, distinguishable from ordinary root rot by the presence of sticky secretions.
Fuso莲花 Scale Insect Control Plan
Physical Removal Stage
Initially, use a soft brush dipped in 75% alcohol to clean each leaf individually, focusing on the axillary parts where eggs are found. After treatment, isolate and observe for 10 days to avoid cross-infection.
Natural Control Methods
Dilute white vinegar solution at a ratio of 1:200, or use fermented orange peel liquid, spraying twice a week. On rainy days, the plants can be kept outdoors, allowing natural rainfall to wash away any remaining pests.
Chemical Application
For persistent infestations, it is recommended to use a 40% omethoate emulsion diluted 1500 times, or alternately use imidacloprid wettable powder. Bagging and suffocating the pests for 6 hours after application can enhance the effect.
Key Points for Fuso莲花 Pest Prevention and Care
Environmental Regulation
Maintain a day-night temperature difference of 8°C, with air humidity below 60%. Apply diatomaceous earth to the surface every quarter to create a physical pest control layer.
Proper Use of Pesticides
Do not use emulsions in winter, instead use (Y-J) type aqueous solutions. Apply pesticides during low light periods, with the concentration strictly controlled at 80% of the recommended value on the label.
By combining physical removal, biological control, and chemical management in a three-level treatment system, along with environmental regulation, scale insects can be effectively eradicated. Regularly inspect the back of leaves during routine maintenance, and preventatively use garlic extract to significantly reduce the incidence of pest infestations.
